Effect of Different Levels of Indole-3-butyric acid on Growth, Development, Survival and Establishment of Air Layered Lemon (Citrus limon L. Burm.) Cv. Assam Lemon under Allahabad Agro-climatic Condition

This experiment was conducted to evaluate the best treatment combination among IBA, Seaweed Extract and Phloroglucinol concentration for assesing the success rate, survival percentage of Kinnow. The experiment was laid out in Randomized Design having 12 treatments and replicated 3 times. The T7 IBA@2000ppm+Phloroglucinol@5000ppm recorded highest values in terms of success in rooting percentage (73.67), number of days taken for initial root formation (28.44), root length of layers (7.30cm), number of roots per layering (20.44), root thickness (3.70mm), number of new sprouts per layer (6.56-1MAP, 8.89-2MAP, 8.56-3MAP & 8.00-4MAP), number of new leaves per layer (6.67-1MAP, 10.56-2MAP, 7.09-3MAP & 12.78-4MAP), length of new shoots (4.26cm-1MAP, 5.23cm-2MAP, 7.09cm-3MAP & 9.94cm-4MAP) and survival percentage of rooted polybag transplanted air layers (68.66%) respectively in Kinnow, whereas minimum values were recorded in T6 (IBA@3000ppm + SWE@5000ppm).

“…Physiological basis of layering involves accumulating organic substances like carbohydrates, hormones, and growth factors in a stem where rooting is desired by interrupting their downward translocation from the shoot tips and leaves [17][18][19]. The rooting ability of layering can be improved by preconditioning treatments such as etiolation, girdling, periderm stripping, and application of growth regulators like auxins.…”

The present investigation was carried out in the Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj in August 2022 to December 2022. The experiment was conducted to evaluate the best IBA concentrations among different concentrations of IBA for producing best layering and survival percentage in Olive. The experiment was laid out in Randomized Block Design having 8 treatments and replicated 3 times. The treatment T4 in which IBA 4000 ppm was applied for air layering was found to be best in terms of shoot and root parameters observed, i.e., Number of days to root formation (46.11), Number of roots per layer (7.33), Root length (6.73 cm), Root thickness (1.66 mm), Number of new sprouts (2.67-1MAP, 3.89-2MAP & 5.67-3MAP), length of new shoot (2.78cm-1MAP, 3.73cm-2MAP & 5.44cm-3MAP), Number of new leaves (7.22-1MAP, 10.78-2MAP & 16.56-3MAP) and survival percentage (50.89%) in air layered olive plants, whereas minimum values were recorded in T8 (control). It can be inferred from this study that, the use of IBA 4000 ppm was effective to produce better root and shoot parameters and successful establishment of air layers in olive.

“…seedless lemon is the principal lemon cultivar of the North to Central region of India. Lemon fruit is medium large, long elliptic to oval, base rounded, nipple broad but low, rind medium thick, firm, surface very smooth, shinning, yellow colour, segments 9-12, axis hollow, pulp vesicle crystal white, juice abundant, acidic, fruit weight (g) 81.33, peel thickness (mm) 1.73, number of segments 10.67, seeds/ fruit 0 or 1, TSS 7.33, acidity (%) 7.90, flavor good, usually seedless, occasionally contains a few seeds [1]. In India the "Seedless" lemon is profuse and among the prime lemon cultivar.…”

Study Design: Randomized Block Design. Place and Duration of Study: Department of Horticulture, College of Agriculture, RVSKVV, Gwalior, MP between 2018 - 2019. Methodology:In 2018-19 the study conducted amidst rainy season and Gird agro-climatic context of Madhya Pradesh to evaluate the effect of phytohormones on rooting and establishment of seedless lemon air layers. Experiment consisting nine treatments replicated three times under Randomized Block Design. Treatments comprising of two plant hormones namely IBA and NAA each with four concentration levels i.e. 1250, 2500, 3750 and 5000ppm including control. Plants age were seven years. Results:The results revealed maximal rooting percentage (92.00), number of primary roots (22.72) and secondary roots (49.97), length of primary roots (5.05 cm) and secondary roots (2.25 cm), diameter of primary roots (1.68 mm) and secondary roots (0.84 mm) and dry weight of roots (2.32g) and planted air-layers (89.21 %) were recorded with application of IBA @ 5000ppm. Conclusion:Indole-3-butyric acid performed better than naphthalene acetic acid for promoting rooting and establishment in seedless lemon air-layers. Application of IBA @ 5000ppm significantly increased rooting characters followed by NAA @5000ppm for better establishment of Lemon air layers for its propagation.
